※ If you purchase this with the separately listed sake cup, we will discount the set to 3000 yen. Please comment if interested. This is a porcelain ochoko (small sake cup) made by Senryu Shuzo, the brewery that produces the Nagasaki sake "Honjin." I believe it is Mikawachi ware. Excerpt below: The unique design of the ceramic ware, known as "Karako," is famous throughout the country as the kiln mark design of the Hirado Domain Lord Matsura's official kiln. This color Karako design is a faithful reproduction on a yunomi (teacup) or guinomi (sake cup) of the design written on the Matsura Lord's exclusive matcha bowl, which was kept and passed down at the Matsura Honjin residence during the Edo period, when traveling to and from Nagasaki. We hope you will cherish it, reminiscing about the past. Hirado Road ∴ Honjin Brewing Thirteenth Generation Shozaemon Yamashita
